Specification of Letters Patent. Patented Mar. 26, 1918.

Application filed February 16, 1916. Serial o. 78327.

To all whom it may concern: 7 Be it known that I, VVILL'IAM H.

phia and State of Pennsylvania, have in vented certain new and'useful Improve ments in Auto-Treads, of which the follow- 'ing is a specification.

thereby giving more power to the driving wheels and onethatadds greater resiliency to the shoe owing to the fact that it takes advantage of the entire diameter of the shoe. Also a tread that prevents skidding side- .wise due to the metal running at right angles to the direction of skidding and other objects as will hereinafter appear. 7

I attain these objects. by means of the mechanism illustrated in the accompanying drawings in which- Figure 1, is a plan view of the device look ing down on top of the wheel;

Fig. 2, is a sector of an auto wheel showing the rim, shoe, and tread in their relative posltionsr Fig. 3 is a transverse sectionof the device on line 33 of Fig. 1.

Similar letters refer to similar parts I throughout the drawings.

The rim or is supported by the spokes b in the ordinary way and the shoe 0 is attached to the rim and the tread cl is'attached to the shoe 0. The said tread d consists of a series of vertical laminated links 6 compris COURTE' NAY, a citizen of the United States, residing at Philadelphia, in the county of PllllElClGlr.

ing a continuous treadaround the entire periprehy of the shoe 0 and are here illustrated as an integral part of the shoe but may be constructed separately and attached in any convenient manner to any kind of shoe.

Said laminated links e consist of layers of metal and fiber, or leather, rubber or other suitable material, alternately, as shown at f. The said layers of metal and fiber, or

other suitable material, or laminations comprising each separate link, are securely riv' eted together by means of the rivets g.

The series of laminated links a are connected flexibly together by means of the .metal pin h. A strip i of asbestos, felt, or

other suitable non-conductor of heat is provided as shown to prevent the metal of the tread from coming in direct contact with the inner tube of the tire.

Having described my invention, what I claim as new and desire to secure by Letters Patent is t In combination with the rim of an auto wheel having a shoe attached thereto of an auto tread attached 'to saidshoe, comprising a series of'vertical laminated links, the laminations of "each separate link being riveted together, and ametal pin flexibly connecting each separate link with the other links so as to form a. continuous tread around the entire periphery of said auto shoe, all substantially as shown and described.

In testimony whereof I affix my signature inpresence' of two witnesses.
